Method for Rendering of Augmented Reality Content in Combination with External Display

2. The method of claim 1, wherein the at least one visual parameter includes a luminance of the screen content, and wherein the transformation includes a transformation of brightness of the virtual content.

3. The method of claim 2, wherein the determined luminance of the screen content is a maximum luminance in the captured region of screen content.

4. The method of claim 2, wherein the transformation comprises a gain factor applied to color code values of the virtual content, and wherein the gain factor increases for increased determined luminance of the captured region of screen content.

5. The method of claim 1, wherein the at least one visual parameter includes a white point of the screen content, and wherein the transformation includes a transformation of a white point of the virtual content.

6. The method of claim 5, wherein determining the white point of the screen content comprises applying a grey world algorithm to the captured region of screen content.

7. The method of claim 1, wherein the image of the real-world scene is captured using a forward-facing camera of the augmented reality display.

8. The method of claim 1, wherein the augmented reality display is an optical-see-through head-mounted display.

12. The apparatus of claim 11, wherein the at least one visual parameter includes a luminance of the screen content, and wherein the transformation includes a transformation of brightness of the virtual content.

13. The apparatus of claim 12, wherein the determined luminance of the screen content is a maximum luminance in the captured region of screen content.

14. The apparatus of claim 12, wherein the transformation comprises a gain factor applied to color code values of the virtual content, and wherein the gain factor increases for increased determined luminance of the captured region of screen content.

15. The apparatus of claim 11, wherein the at least one visual parameter includes a white point of the screen content, and wherein the transformation includes a transformation of a white point of the virtual content.
